Spray polyurethane foam (SPF) is one of the fastest growing building insulation products globally. SPF can help reduce energy use in new and existing buildings. Up to 40 percent of U.S. energy demand is consumed by buildings, and according to the U.S. Department of Energy, as much as 40 percent of a building's energy is lost due to air infiltration. SPF functions as both an insulation material and an air-sealing product. In buildings insulated with SPF, utility cost savings of up to 50 percent can be achieved.

Huntsman's methylene diphenyl diisocyanate (MDI) is used as the "A-side" ingredient in many SPF systems. Additionally, Huntsman offers a full range of SPF raw materials including polyols, catalysts and other additives used to formulate the "B-side" of SPF systems.
